Excavations of the Kuwaiti–Polish Archaeological Mission at the site of Bahra 1 in Kuwait uncovered the remains of a large settlement from the sixth millennium BC, associated with the Mesopotamian Ubaid culture. This connection is made clear by the presence of Ubaid Ware from the Ubaid 2/3 phase that appears alongside Red Coarse Ware typical for the Arabian Neolithic. Architecture of the settlement resembled the Ubaid one with orthogonal, multi‐chambered houses. In one part of the site they form a dense block with traits that indicate some degree of spatial planning. This type of spatial arrangement is absent in Arabian Neolithic settlements and is also unknown from Ubaid settlements in Mesopotamia. One of the buildings discovered at Bahra 1 has a ground plan reminiscent of a sanctuary from Eridu XVI and was probably associated with cultic activities, as was a circular stone enclosure (Unit 6), representing local building traditions. The character of Bahra 1 architecture and the presence of cultic buildings at the site suggest that the settlements served as a local ceremonial and/or cultic centre.
